Zinc 500 - Instrument Amplifier

Zinc is a universal instrument amplifier in 500-series format.

The instrument amp uses the input from the rack, and has a gain range of -20 to +20dB
Switching to the Z-in on the front panel, the gain range becomes 0 to 40dB

The glow function works on either input and introduces valve (tube) distortion (2nd and 3rd harmonics). Try it !

The Z-In Ω rotary switch changes the input impedance of the Z-input, actually changing the tone.
This is most effective on electric guitar, but can be used on anything you like.

Zinc features our reference bargraph meter.
